Legal claims defining the scope of protection, as filed with the USPTO.
1. A touch sensor comprising first and second electrodes each comprising an interconnected mesh of conductive traces, the first electrode comprising all upper conductive traces in the touch sensor and the second electrode comprising all lower conductive traces in the touch sensor, the first and second electrodes crossing over one another in a cross-over area, the first and second electrodes having variable mesh densities in the cross-over area complementary to one another across the entire cross-over area.
2. The touch sensor of claim 1 further comprising a dielectric layer disposed between the first and second electrodes.
3. The touch sensor of claim 1 , wherein the conductive traces in each of the first and second electrodes form a random network of conductive traces.
4. The touch sensor of claim 1 , wherein the conductive traces in each of the first and second electrodes form a pseudo-random network of conductive traces.
5. The touch sensor of claim 1 , wherein the conductive traces in each of the first and second electrodes form a regular network of conductive traces.
6. The touch sensor of claim 1 , wherein the conductive traces in each of the first and second electrodes comprises silver.
7. The touch sensor of claim 1 , wherein the conductive traces in each of the first and second electrodes are curved.
8. The touch sensor of claim 1 , wherein the conductive traces in each of the first and second electrodes are straight.
9. A touch sensor comprising first and second electrodes each comprising an interconnected mesh of conductive traces, the first electrode comprising all upper conductive traces in the touch sensor and the second electrode comprising all lower conductive traces in the touch sensor, the first and second electrodes crossing over one another in a cross-over area, each of the first and second electrodes comprising a two-dimensional mesh in the cross-over area, wherein in the cross-over area: a first region of the first electrode having higher mesh density overlays a first region of the second electrode having lower mesh density; a second region of the first electrode having lower mesh density overlays a second region of the second electrode having higher mesh density; and a third region of the first electrode overlays a third region of the second electrode, the two third regions having equal mesh densities.
10. A touch sensor comprising first and second electrodes each comprising interconnected mesh of conductive traces, the first electrode comprising all upper conductive traces in the touch sensor and the second electrode comprising all lower conductive traces in the touch sensor, the first and second electrodes crossing over one another in a cross-over area, the first electrode having a uniform mesh density across the entire cross-over area, the second electrode having a variable mesh density across the entire cross-over area.
